Network meta-analysis combines direct and indirect evidence to compare multiple treatments. As direct evidence for one treatment contrast may be indirect evidence for other treatment contrasts, biases in the direct evidence for one treatment contrast may affect not only the estimate for this particular treatment contrast but also estimates of…

The purpose of this study is to examine the effect of material incentives on the knowledge-sharing networks and information lifecycles of a public online forum. The users' interaction data were collected from two similar sub-forums, and one of them provided material incentives for sharing knowledge. After collecting user behaviors for one natural…

Network meta-analysis (NMA) is an established method for assessing the comparative efficacy and safety of competing interventions. It is often the case that we deal with interventions that consist of multiple, possibly interacting, components. Examples of interventions' components include characteristics of the intervention, mode (face-to-face,…

This article introduces a network approach to describe the quality of written scientific explanations. Existing approaches evaluate explanations mainly on the level of sentences or as a whole but not on the elementary level of single terms. Moreover, evaluation of explanations is often based on highly inferential scoring techniques. We addressed…

Doctoral work is often characterised as lonely and isolating (Holbrook et al. 2014). This paper explores how collaboration with peers and other professionals supports the doctoral learning experience. The research study asks what networks doctoral students engage with and how their engagement in networks supports their studies. Semi-structured…

Effect modification (EM) may cause bias in network meta-analysis (NMA). Existing population adjustment NMA methods use individual patient data to adjust for EM but disregard available subgroup information from aggregated data in the evidence network. Additionally, these methods often rely on the shared effect modification (SEM) assumption. In this…

Purpose: School leaders rely on a number of collaborative policy tools to address fiscal and governance issues. While prior research has examined the dynamics and implications of research-practice and public-private partnerships, this study addresses a third form of collaboration: interdistrict cooperative agreements. Method: We develop a unique…

Built environment research has long been interested in understanding the complexities of transitional spaces by investigating their hosted interactions. One approach used in efforts of this kind is actor-network theory (ANT), which conceptualizes built spaces as networks of relations that allow for certain interactions but not others. Previous…

This thesis consists of two projects I worked on simultaneously throughout my PhD. Although neither project builds on the other, both investigate social systems as networks, and draw on a common set of statistical tools and methods.In the first project, I analyse the academic employment and doctoral education of tenure- track faculty at all…

The main goal of this article is to analyse the Non-Partisan School movement (EsP, or Escola sem Partido) which articulates social and political actors around a conservative agenda for education in Brazil. Based on Ball's studies, this article analyses political governance networks using a free software, GEPHI, using a qualitative network…

The purpose of this dissertation is to study the consistency of the structures and the centrality of mathematics courses in the curricula of the universities in the Minnesota State University system. This research will be based on the curriculum prerequisite networks for the seven universities in the Minnesota State System. These networks will be…

Online laboratories have been widely used in education, research, and industrial applications. For online laboratories, various architectures have been constructed to provide good user experience and powerful capabilities for online experimentation, in which the controller is a crucial part to connect the server with a controlled test rig.…

This paper presents the results of a study that investigated technical and professional educational policies in both Brazil and Mexico, and the relations of these two countries with international networks of educational organizations. The focus is on the three international organizations that have had the most influence on public education…

The field of higher education research is fast-growing, both in number of publications and in geographical reach. There is however limited evidence on how this growth in publication influences the structure of the underlying co-authorship network. This is important as structural network parameters can change quickly in a fast-growing network,…

The purpose of this paper is to introduce citation networks, a novel method for identifying field connections, and to elaborate a theory of spatiality that deploys the metaphors of bubbles and foams to imagine space and change. After introducing the method and theory that guide this investigation, the author will introduce and describe the foams…
